RECEPTACLE FOR CONTAINING AND DISCHARGING SEMISOLID AN D PASTY SUBSTANCES.

Specification of Letters I'atent.

Patented May 7, 1912.

Application filed October 14, 1910. Serial No. 587,081.

Il'o all whom it may concern:

Be it known that I. JAMES F. CRAVEN, a resident of Pittsburgh. in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Receptacles for (ontaining and Discharging Semisolid and Pasty Substances, of which the following is a specification.

This invention relates to receptacles for containing, storin' transporting and discharging semi-solid and pasty substances.

The device is intended more art-icularly for putting up lubricants in tile form of grease and discharging the same into the grease cups of machine or the like and for y the )urpose of enabling grease to be supplied to the hearings without liability of dirtor grit entering the bearing with the grease, and also to prevent smearing up or soiling the hands of the workman or the machinery. The invention, however, is not limited to this particular use, but is adapted for putting up in a substantially sealed condition any semi-solid or pasty substance and delivering the same from the container in any desired quantity or quantities.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawing Figure 1 is a vertical section through the device; and Fig. 2 is a vertical sect-ion of the upper portion of the device in a plane at right angles to that of Fig. 1.

The container or receptacle may be of any desired size or shape, and may be constructed or built up in any desired way or from any desired material. As shown, the receptacle is formed from a substantially cylindrical tube 1 which may be of sheet metal or other thin substance and as shown is formed from paste or paper board. One end of this receptacle is closed by the head :2 which is shown as composed of sheet metal crimped onto the end of the paper tube. The other end of the receptacle is closed by means of the head 3 provided with the central discharge opening 4 formed in the threaded projection 5 which may be closed by means of an' ordinary screw cap 6. The head is also crimped onto the paper tube,

. but if desired it may be removably secured to the receptacle or tube 1, such as by means of threaded connection with a threaded ring crimped on the tube. in order that the. same may be taken off for the purpose of filling the receptacle. This latter, however, is not necessary. as the receptacle can be filled through the discharge opening 4:. The threaded projection 5 also serves to have screwed thereon a delivery spout 7 when discharging the material from the receptacle. v

In the recept-acle'l is a movable piston or follower 10 provided with a cup leather 11 or other suitable means providing for a close fit in the receptacle and being yielding so as to maintain a tight fit in the tube in case the latter expands under the pressure of forcing out the substance contained therein. The piston or follower is shown as a solid disk of wood or other suitable material, althoughif desired it may be stamped up of sheet metal. In order to force the material from the container the piston is moved longitudinally in the tube or receptacle 1. The means for effecting this comprises a suitable flexible member 12, such as a cord, band, wire or the like, which has one end secured centrally to the piston 10 as at '13, and then passes over a suitable support at the delivery end of the receptacle and thence returns and passes through a hole 14 in the piston, and a similar hole 15 in the head 20f the receptacle, and is provided on the outside with a suitable handle 16, loop or other means which can be readily grasped for pulling.

The support at the discharge end of the receptacle may be of various forms, that shown comprising a bar 18 soldered or otherwise secured at its ends to the cap or head 3 and over which the flexible member 12 passes. referably a small sheave 20 is mounted on said bar to reduce friction. The bar shown is a piece of round wire on which the flexible member 12 could have a direct bearing without the use of the sheave 20.

In use the receptacle is filled with the grease or other substance at the factory, being filled through the discharge end and while the piston is in the oppos te end of the receptacle. Preferably the filling Wlll be done through the discharge orifice 4 as this enables the cross bar 18 and the wire or band 12 to be in proper position. \Vhcn the receptacle is filled it is closed by means of cap 6, and can then be conveyed to the place of use. It presents a substantially smooth exterior, there being-no projections on the outside except the loop or 'handle- 16. In

use the cap 6 is unscrewed, and if desired.

a the delivery spout 7 is screwed on to the hands of the workman or carrying grit or.

dirt into the grease cup. When the desired uantity of material has been discharge the cap 6 may again be screwed into lace and the receptacle remains in this conition until necesslty for further use. \Vhen used for containing butteror the like the' contents are protected against the absorption of odors from other substances stored nearby.

The receptacle is intended to be used only once, being filled at the factory and thrown away when emptied. Hence it must be of low cost and necessarily is made of cheap and comparatively weak material and with,

minimum labor operations. A paper or paste board tube is therefore referred for the body of the rece tacle, but if sheet metal is used it will be 0 the thinnest gage. On account of the cheap, light construction of the tube it is liable to expand slightly, or assume a slight barrel shape under the ressure of forcing the stiff grease out o the same. The cup leather 11 or similar means is however expansible and in effect forms an expansible piston or follower so as to maintain a'tight fit against the inner wall of the tube-and prevents the grease from wasting by escaping past the edge of the follower.

What I claim is: E

1. A device of the character described comprising a fiber tube, a head closing one end ofsaidtube and provided with a discharge orifice, a bearing member secured to said head and extending across said discharge orifice, a piston or follower in said receptacle arranged when moved to force the substance out of said discharge orifice. and a flexible member connected to said piston and passing over said bearing adjacent to the discharge orifice and thence extend.- ing to the outside of the receptacle and arranged to be pulled upon to move the piston toward the discharge orifice.

2. A device of the character described comprising a fiber tube having an interior unobstructed from end to end. heads closing the ends of said receptacle. one-of said heads being provided with a discharge orifice. a bearing member'secured to said last named head, a piston insaid receptacle arranged to be moved from end to end thereof to force the contents of the discharge 0rifice. and a flexible member secured to said piston and extending over said bearing member and thence extending to the opposite end of the receptacle and through the head thereon and provided, outside said receptacle with means to be grasped and pulled.

In testimony whereof, I have hereunto set my hand.
